Instagram is a popular image sharing social network. If you're a regular user of the app, you should have a good idea that it doesn't offer top-notch experience when it comes to desktop. If you're looking for a decent Instagram client for Windows, take a look at Grid for Instagram.
The app comes with a very simple and responsive user interface to help you easily navigate in the news feed. The app further allows users to log in with multiple accounts, as well as support for notifications for new feed, followers, likes, comments, mentions or requests. Furthermore, it automatically adjusts layout depending on the Window size you're using, resulting in an improved user experience, show users tagged in a photo and lots more.
The free version of the app is available for download through the developer's website, but to unlock the full potential of the app, you have to purchase the full version. The app is compatible with Windows XP, Vista, Windows 7, Windows 8 and Windows 10 as well.
